ERBB2 and nasopharyngeal carcinoma: To further investigate whether miR-940 and ERBB2 are functionally relevant in NPC, we performed rescue experiments showing that upregulation of ERBB2 reversed the overexpression of miR-940 on proliferation, migration and VM formation in NPC cells, whereas downregulation of ERBB2 reduced the enhancement of proliferation, migration and VM formation induced by miR-940 silencing (Figs. 2F–2H).
